What does "Rise Up" by Imagine Dragons mean?

I've already explained seven out of the eleven songs on Evolve, and I'm not going to explain every song on the album. Two of the ones I've explained so far have been unfortunately rather shallow or rather vague in a "pop music sort of way" that leaves me wanting something deeper from Dan Reynolds and Imagine Dragons. So, to make sure that I wasn't wasting time, I looked at the last four I hadn't explained yet and decided that "Rise Up" was likely the deepest one I hadn't explained. The song's interesting, written almost entirely by band members, and focuses on a theme of improving one's self. Let's see if it stands up to explication.
